Thank you for waiting

aconran,

I released the left mouse button when i wanted to scroll screen up to expand the border more towards bottom. but the border was following mouse pointer and then border was running away from mouse pointer. I was making change in my same project i uploaded for you on github https://github.com/jaami/Sencha-Arch...2-bug-tracking

Yes, the last option was to set properties manually.

right now i am stuck on another strange issue that is taking my time. I will try my best to write every step to reproduce the same resizing error. meanwhile you can download my project and check resizing issue on CCI view.
